IpWatts

IpWatts is an software to log the information from multiple ANT ™ bicycle energy sensors concurrently to a single .csv file. Invaluable if you would like to compare a number of power sensors in the true world. As nicely as the ability knowledge the app logs pace, cadence and heart fee if that knowledge is available.

If you want a standard bike computer try my biking laptop IpBike which uses the same underlying ANT decode app IpSensorMan but puts a complicated front end onto it. It dose a much better job at presenting and logging the information for most standard users with mapping, direct upload support in addition to interval training capabilities and more.

If you employ this application and publish outcomes I would ask you to acknowledge using the app and ideally hyperlink to it and IpBike in Google Play. Please feel free to e mail me with any issues. I consider this to be beta till it has had some more actual world use, which given the specialist nature of the app could take some time.

IpWatts uses IpSensorMan to do the precise ANT interfacing you will be prompted to install it if you don't have it. You will need an ANT capable telephone or a USB ANT stick and a USB Host capable cellphone.

You will first must pair the sensors manually with IpSensorMan. Just go Start Ant then Search sensors. If there are multiple sensors active then go search sensors again to get another one open. You actually need to try and begin them up one at a time though if possible so that you may be sure which is which. You can press on a sensor within the listing and then identify the sensor to make it distinguishable.

Having added the sensor just open IpWatts it's going to look for a single instance of the usual biking sensors coronary heart fee. Data from these is displayed on the top or left. It then opens as many other energy sensors as it could, you get a list of the sensors with the current energy value. You can calibrate a sensor by pressing it in the record. Once all the sensors you want are in the record just press begin recording. When your accomplished press cease recording. After urgent begin you'll have the ability to go away the primary IpWatts display screen and recording will carry on within the background.

The logged file shall be on the sd card in /Android/data/com.iforpowell.android.ipwatts/files/internal_logs/ the file name will be distinctive.

The knowledge consists of a time stamp column followed by pace, cadence and Heart rate. Then for every power sensor 4 columns. First the watts value, then the accumulated Watt seconds value, then the pedal % or 127 if it isn't out there. Finally there is a 1 or 0 to point if information was obtained on this second, this should permit you to see if there are bad reception issues. If data is not acquired then it is latter crammed in with the following good worth which should be the typical over the dangerous reception interval supplied the hole is not too massive. For the amassed Watt seconds the worth will just keep the identical during dangerous reception however then catch up on a good event. The pedal % can not be relied upon with unhealthy reception, I just put within the final worth. The speed is assuming a 2070mm wheel and is in m/s so you probobly need to do some spreadsheet work to convert it to your required worth.

Things look to be working with up to 4 power sensors with the simulator although it’s exhausting to simulate unhealthy reception very nicely. With the current search methodology I use there's a maximum of 4 sensors of any kind. You ought to be succesful of have IpBike lively concurrently with IpWatts.
